Device to increase intra-abdominal compartment pressure for the controlling of internal hemorrhage

ABSTRACT

A device to increase intra-abdominal compartment pressure for the controlling of internal hemorrhages is presented. The device controls internal hemorrhaging by supplementing the occlusion effectiveness of a pneumatic tourniquet with a shaped device that increases the overall internal pressure in a human compartment, such as the upper abdomen, to assist in the cessation of bleeding in that region. One side of the device includes a flat base that is adapted to be placed against a patient at the targeted body site. The other side has a generally corrugated shape that is sized to receive an inflatable, wedge-shaped bladder from the pneumatic tourniquet. The overall shape of the invention includes a tapered upper end that corresponds with the inferior angle of the lower ribs in a human torso so that when pressed against the patient by the pneumatic tourniquet bladder a uniform distribution of pressure occurs over the upper abdomen region.

FIELD OF THE INVENTION

The present invention relates generally to hemorrhage devices and in particular devices for increasing human cavity pressures to control bleeding. The invention also relates to emergency devices to achieve the cessation of bleeding in a patient's abdomen.

BACKGROUND OF THE INVENTION

A good many deaths result each year from blunt trauma injuries, such as resulting from automobile accidents, aircraft crashes, or bad parachute landings. Dealing with these severe blunt trauma injuries in the field is a nightmare for emergency responders, especially when such trauma occurs to the abdomen. Trauma to the abdominal can result in kidney, spleen, or other solid organ hemorrhages, and often leads to death. For example, a significant spleen laceration can kill a patient in 5-10 minutes if that patient does not receive immediate emergency medical surgery. The standard practice for an emergency responder when abdominal trauma is noticed is to transport the patient as quickly as possible to a hospital where tests can be administered to identify severe bleeding and perform emergency surgery to stop the bleeding. However, quite often transport to a hospital is unavailable or a hospital may be so far away that even under the best transportation scenarios the patient may expire in-route. Further, internal abdominal hemorrhages may not even be identifiable to an emergency responder until systemic symptoms in the patient emerge and by then the patient may only have a few minutes to live.

Field appropriate mechanical and pneumatic tourniquets for the abdomen exist and provide some assistance for abdominal trauma. For example, the Same Junctional Tourniquet (“SAM”), the Combat Ready Clamp, or “CRoC” as it is often referred to, which is simply a large mechanical “C” clamp,” and a pneumatic tourniquet offered under the tradename “Abdominal Aortic Tourniquet” or “AAT” are all known and utilized for field trauma victims. However, these solutions tend to be designed for known, specifically located traumas and hemorrhages that can be directly observed and monitored. In addition, these solutions are often inadequate to stop bleeding for internal organ lacerations in the abdomen caused by blunt trauma because the exact location and severity of the laceration often cannot easily be ascertained. For example, the “CRoC” will not assist in stopping an internal abdominal hemorrhage unless that hemorrhage is located relatively close to the surface of the body of the patient and its exact location also known so that proper placement of the compressing member in the CRoC may be applied to the bleeding location.

Pneumatic tourniquets are another potential solution. Pneumatic tourniquets use pneumatic pressure and generally are a targeted application of external pressure to an area of the body to stop blood flow in major blood vessels, such as in the abdomen of a patient. The bladders of a pneumatic tourniquet focus pressure energy under field medic expertise and direction to cause an occlusion of a primary internal blood vessel, such as the aorta. However, the effectiveness of a pneumatic tourniquet is dependent somewhat on the ability for a field medic to recognize the source of the internal bleeding and properly position the pneumatic tourniquet on a patient's abdomen, and such focused pressure while providing some benefit may not stop a hemorrhaging organ such as a spleen from bleeding because it is also supplied with blood from ancillary blood vessels. Further, field responders often have no idea whether an inter-abdominal hemorrhage has occurred, and may not recognize that a pneumatic tourniquet can assist in stopping the hemorrhage. Finally, improper placement or operation of the pneumatic tourniquet may render it ineffective or reduce its effectiveness.

Hence, a medical device is needed for emergency responders to utilize to quickly stop internal abdominal hemorrhaging, at least for a time, until a patient may arrive at a proper medical facility for surgical treatment to the injury.

Such a medical device may be best used in association with pneumatic tourniquets such as described in U.S. Pat. Nos. 8,834,517B2 and 9,149,280B2. As disclosed in those patents, the pneumatic tourniquet inventions include structures for applying pressure to the torso area of the human body and the present invention is preferably inserted on the inner side of a pneumatic tourniquet and pressure applied with the operation of the pneumatic tourniquet, such as during inflation.

For example, referring to FIG. 6 of U.S. Pat. No. 9,149,280B2 with those noted elements, pneumatic tourniquets include some minimal structures to function, such as a base plate 18, an inflatable bladder 20 depending downward from the base plate, sometimes connected to the base plate through a foam pad 48 to reduce the impact of the plate on the bladder, an air supply line 60 to fill the bladder, a pressure relief valve 62, and an air bulb pump 58. Pneumatic tourniquets also typically include a waist strap 16 that encircles and secures the pneumatic tourniquet to the patient, including a quick connect buckle 68 and a compression latch 30 for compressing and adjusting same. FIG. 6 of U.S. Pat. No. 9,149,280B2, and the disclosure between Col. 5, line 47 through Col. 6, line 50 of U.S. Pat. No. 9,149,280B2, are hereby incorporated by reference. It will be noted that all pneumatic tourniquets include shaped bladders such that the lower edge of the bladder contacting the patient is less wide than the upper portion contacting the base. This tends to form the bladder into generally a “V” shape having the narrow edge at the lower portion of the bladder contacting the patient upon which it is used.

Therefore, a supplemental device used in association with a pneumatic tourniquet will assist in addressing an abdominal hemorrhage in the field and potentially save lives when imperfect knowledge of a patient's actual internal bleeding condition is known or when timely extraction of a hemorrhaging patient to a surgical facility is impossible.

SUMMARY OF THE INVENTION

It is the object of the present invention to control internal hemorrhaging by supplementing the occlusion effectiveness of a pneumatic tourniquet with a shaped device that increases the overall internal pressure in a human cavity, such as the upper torso, to assist in the cessation of bleeding in that region. The present invention includes two pieces of rigid plastic placed in opposing position to one another and coupled with grommets or heat welding. One side of the device is a flat base that is adapted to be placed against a patient at the targeted body site. The other side has a generally corrugated shape that is sized to receive an inflatable, wedge-shaped bladder from a pneumatic tourniquet. The overall shape of the invention from a plan perspective is rectangular, but the invention has corners cut on one end to form to an angle that corresponds with the inferior angle of the ribs. Other features and objects and advantages of the present invention will become apparent from a reading of the following description as well as a study of the appended drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings for a better understanding of the structure and use of the invention, FIGS. 1A-1C provide views of the invention 10 showing the basic elements of the device. Each device 10 includes a lower or base portion 11 that supports an upper corrugated top portion 12. Lower portion 11 is substantially flat and includes a leading edge 21 and a trailing edge 22. Leading and trailing edges are connected along the undersurface 14 of lower portion 11 of the device and along left and right edges 26 and 27. The upper portion 12 and the lower portion 11 are fused at the leading and trailing edges 21, 22 through a series of grommets 17,19 to form a unified body.

As may be seen, upper portion 12 is corrugated such that two upper ridges 13 a,b are formed in parallel orientation with respect to leading and trailing edges 21, 22. The two ridges 13 a,b form a parallel valley or recess 15 between them that will receive a portion of a pneumatic tourniquet bladder, as will be discussed.

Referring now also to FIGS. 1B and 1C, it may be seen that the device 10 has a generally rectangular in shape with the leading edge 21 having a width substantively less than trailing edge 22. The side edges of upper portion 12 match the side edges of lower portion 11 to form a tapered shape of the device 10 at one end in which approximately a third of the perimeter of the device tapers along the edges 26/27 to the extents of the leading edge 21 as shown. In particular, edges 26/27 include a straight segment edge portion 32 a,b and an angled segment portion 31 a,b. Tapered edges 31 a,b taper from points 28 a,b to leading edge points 29 a,b forming an angle of approximately 135 degrees at the juncture of segment edges 32 a,b and segment edges 31 a,b, respectively. As may be better seen in FIG. 1C, ridges 13 a,b form hollow spaces 23 between base portion 11 and top portion 12 having a generally triangular shape.

The combination of straight side edges 32 a,b and tapered side edges 31 a,b form a outline shape in the device 10 that conforms to a typical inferior angle of the lower ribs of the human torso.

The device 10 may be constructed from two separate pieces of plastic to form the base and top portions 11/12. The base portion is generally flat and acts as a base for the device and contacts directly against a patient. Some minor ribbing features (not shown) may be formed into the underside or lower surface 14 of base portion 11 to strengthen and provide it with additional rigidity. Horizontal ridges 13 a,b are thermally formed into upper or top portion 12 that results in the recess 15 which is shaped to receive and capture a lower portion of a pneumatic tourniquet bladder applied over the device 10. While the device 10 is described with upper and lower portions 11/12 fused with grommets, it will be understood that these portions may be fixed together through adhesives or with heat welding, or any other suitable method to ensure sufficient bonding and resilience such that upper and lower portions are fixed in orientation and shape. Recess 15 presently is not fixed against the upper surface of base portion 11 because due to the resiliency of the upper portion plastic it is not necessary, and under tension the recess may simply rest against the upper surface of the base portion if deformed under pressure. However, the inventor anticipates that fusing of the recess undersurface into the upper surface of base portion 11 may be utilized to further increase the overall resiliency of the device 10.

The preferred dimensions of the device are 4 inches along edges 32 a,b, 6 inches spanning leading edge 21 and trailing edge 22, and 7 inches along trailing edge 22. The distance between ridges 13 a,b is approximately 3 inches, forming a slope of approximately 45 degrees down each ridge to the recess 15 and to leading and trailing edges 21/22 at the juncture of the base 11 and top 12 portions. The above indicated shape and size of the invention allows for maximum overlay of critical organs in the abdomen, and also to provide a practical and packable device for a medical field kit. The overall width of the device is also sized so that the recess 15 matches the maximum length of the lower end 126 of the bladder 20 when the two are engaged together.

While the actual ridge heights 13 a,b are not critical, a ridge height of at least 1.5 inches is preferred to avoid rocking of the bladder 20 during inflation, and additional ridge height beyond 1.5 inches actually increases stability during the engagement of the bladder 20 on the device 10.

FIG. 2 provides a copy of FIG. 6 of U.S. Pat. No. 9,149,280B2 and shows a typical pneumatic tourniquet having essential functioning elements, which are described above in the Background of the Invention. The numerals of that FIG. 6 in U.S. Pat. No. 9,149,280B2 are replicated for this disclosure to facilitate discussion.

FIG. 3 shows the pneumatic tourniquet of FIG. 6 of U.S. Pat. No. 9,149,280B2 positioned over a patient with the compression device 10 in place underneath the pneumatic tourniquet with the bladder in a partially inflated state. As noted in that patent, FIG. 3 of U.S. Pat. No. 9,149,280B2 shows a typical pneumatic tourniquet with the hand pump bulb 58 replaced with a CO2 cartridge 28 for inflation. FIGS. 1A-2C of U.S. Pat. No. 9,149,280B2 show the typical positioning of the pneumatic tourniquet on a patient. FIGS. 1A-2C of U.S. Pat. No. 9,149,280B2 and the disclosure spanning Col. 3, line 60 through Col. 4, line 43 of U.S. Pat. No. 9,149,280B2 are hereby incorporated by reference. Further discussion regarding the operation and functioning of the pneumatic tourniquet in U.S. Pat. No. 9,149,280B2 will be restricted to structures and processes intersecting with the compression device 10 since such disclosures are already fully developed in U.S. Pat. Nos. 8,834,517B2 and 9,149,280B2.

Referring to FIG. 3, the pneumatic tourniquet 35 is arranged over the upper abdomen 37 of a patient 36 to apply localized pressure over the higher organs of the torso with the compression device 10 when positioned under the bladder 20. The pneumatic tourniquet 35 includes an adjustable waist strap 16 for securing the pneumatic tourniquet and the compression device 10 on the upper abdomen of the patient 36. The rigid base plate 18 is carried on waist strap 16 and supports the bladder against the compression device 10, and the directed air bladder 20 is carried on the bottom side of base plate 18. The bladder 20 is shown in a deflated condition and may be generally collapsed against base plate 18 until properly positioned against the compression device 10. With partial inflation of the bladder 20, the narrow lower end 126 of the bladder 20 extends and is arranged to be inserted into device recess 15 and held in place as the bladder further expands. As bladder 20 is expanded to extend outwardly from the bottom side of base plate 18 it exerts pressure on the compression device 10 against the patient 36 compressing the upper abdominal area 37. The air source used to inflate the bladder 20 may be a CO2 gas cartridge or a bulb pump 58 as shown. The pneumatic tourniquet 35 may also include a compression latch 30 affixed to base plate 18 and operatively associated with waist strap 16 for tightening waist strap 16 around the upper abdomen 37. Preferably, strap 16 also includes a quick connect buckle 68 to facilitate arrangement of the pneumatic tourniquet 35 around the patient 36 that then allows for the compression latch 30 to be closed.

Referring to now to FIG. 4, it may be seen a patient 36 with a compression device 10 positioned on the abdomen prior to arranging the pneumatic tourniquet 35 over the patient 36. As shown, the tapered end of the compression device 10 is oriented upwards towards a patient's head, but below the ribs of the patient, for compression of the upper-mid abdomen. For usage in lower abdomen and pelvic regions, the device 10 is rotated 180 degrees so that the tapered end is oriented downwards and positioned over the human pelvis with the ridges positioned away from the patient and the lower surface of the base 11 positioned toward and in contact with the patient 36. The pneumatic tourniquet is placed over the compression device and secured around the patient's hips. Slack is removed from the belt of the pneumatic tourniquet and the compression device tightened against with patient at the appropriate site on the upper abdomen. The recess 15 is shaped to receive the bladder lower end 126 as described above such that upon inflation of the bladder and focused engagement of the base 11 against the patient, the compression device 10 and the pneumatic tourniquet 35 are secured and fixed to the patient in a static state, and the upper abdomen is compressed as more air pressure is exerted into the bladder 20. While not always necessary, a windlass (see for example, element 85 of FIG. 8 of U.S. Pat. No. 9,149,280B2) on the pneumatic tourniquet 35 may be utilized to further tighten the pneumatic tourniquet 35 and compression device 10 against the patient, but in either case the bladder 20 is inflated to at least 250 mm Hg pressure. The compression device 10 distributes the pneumatic tourniquet 35 pressure from bladder 20 in a uniform manner and over a larger area than the tapered bladder 20, thereby increasing the intra-abdominal compartment pressure from the exterior pressure application. The combination of the pneumatic tourniquet 35 and compression device 10 also provides pressure in a wedge shaped distribution which is effective at blocking blood flow through arterial vessels to the upper abdominal area. The device uses the flat underside to achieve an equally distributed pressure over the upper abdominal region, and is effective to alter the generally wedge pressure distribution of the pneumatic tourniquet to that of a flat distribution over the upper abdomen.

Referring finally to FIG. 5, it may be seen the preferred steps 40 in utilizing the compression device 10 by a field medic or emergency responder. A patient should be arranged into a prone position on their back 42. The compression device 10 is positioned 43 on the patient with the flat lower surface 11 in contact with the patient's upper abdomen just below the rib cage coastal margins, sometimes referred to as the “costal arch” or “medial margin” area of the lower rib cage, with the tapered end pointing upwards towards toward rib cage. The pneumatic tourniquet 35 is then arranged 46 over and around the patient 36 in a manner that allows for the bladder 20 to be in proximity to the compression device 10. The pneumatic tourniquet 35 is tightened around the patient 36 and the bladder 20 inflated 47 so that bladder's lower edge 126 fills the recess 15 in the compression device 10. It is critical that the tapered end of the compression device 10 be oriented upwards toward and just below the lower rib-cage so that a substantial area of the upper abdomen is affected. As may be understood, the straps 16 and buckles and latches 68/30 would be adjusted so that the pneumatic tourniquet 35 is fitted correctly around patient 36 and over the compression device 10. As may also be understood, steps 43, 46, and 47 may be varied such that the compression device 10 may be positioned on the abdomen of the patient simultaneously with or after the pneumatic tourniquet 35 is fitted over the patient, depending upon practice and training of each medical practitioner to accommodate different patient sizes and shapes, and to adjust to field conditions in which the patient is situated. The bladder 20 of the pneumatic tourniquet 35 is inflated further 49 to a minimum effective pressure of 250 mm Hg exerted against the upper abdomen, but not more than 300 mm Hg pressure. In order to ensure that 300 mm Hg are not exceeded, a medical practitioner may use a manometer connected to pressure tube 60 of the pneumatic tourniquet to monitor the pressure and cease pumping air into the bladder 20, or release air from the relief valve 62, or alternatively the pressure relief valve 62 may be preset to release pressure automatically when the tube 60 pressure exceeds 300 mm Hg. Additional pressure feedback may be provided by the pressure relief valve 62 or another type of pressure adjustment mechanism, as may be understood.

The inventor has observed that an external minimum pressure from bladder 20 results in a minimum inter-abdominal compartment pressure of 40 mm Hg. Hence, a minimum external pressure of 250 mm Hg should be applied to the patient and held for at least 20 minutes to arrest internal bleeding. Such inter-compartmental pressure will not permanently damage the targeted organ or surrounding tissues. After that minimum period of time, cessation of blood flow from solid organs, such as a laceration in a spleen, will abate considerably and quite often will stop entirely. Also, after that minimum timer period, the pneumatic tourniquet pressure may be reduced below the critical external pressure to allow for easier respiration by the patient or for further field examinations. Once the compression device 10 has been pressurized by the pneumatic tourniquet 35 (i.e. after step 49) the patient may be transported 51 to a primary medical facility for further treatment.

While I have shown my invention in one form, it will be obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modifications without departing from the spirit thereof. For example, while use of the invention with a pneumatic tourniquet has been provided as an example, the inventor anticipates that a mechanical substitute may be devised that will allow for the controlled application of pressure to the upper surface of the device 10 for similar satisfactory inter-abdominal pressure results. In addition, various types of textured surfaces such as a non-skid tape or similar material may be applied onto the upper 12 and lower 11 portion surfaces to enhance engagement of the pneumatic tourniquet 35 with the compression device 10.
